This study found that Heterogeneous Victoria A Acid Capsules significantly reduced sebaceous acid capsule diameter and hair follicle size in a rabbit model of micro-acne.

This study found that implanting isolated adult rat dermal papillae into ear cuts led to the emergence of unusually large vibrissa-type hair follicles, demonstrating their capacity to induce specific hair fiber characteristics.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

This study observed an association between intense itching in anterior chest keloids and an increased density of nerve fibers in the epidermis, alongside elevated expression of the pruritus mediator substance P, though no difference was found in Langerhans cells related to pruritus, location, or region.

In this study, skin stretching significantly increased the delivery of retinyl ascorbate into the dermis, while sealing hair follicles did not affect absorption through native skin.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that rubbing increased caffeine permeation into skin primarily via hair follicles, especially when applied against the natural hair direction.

This study found that an acne complex animal model using rabbits showed more pronounced clinical symptoms and measured changes compared to the traditional Kligman model.

In this case report, the authors describe a female dog with alopecia in the neck and ear region, affected by dermatophytosis caused by the zoophilic fungus Microsporum canis, highlighting its zoonotic potential and prevalence in certain climates.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study found that transgenic mice expressing IGF-1 in their skin showed significant skin changes, early hair follicle generation, and a higher propensity to develop tumors after chemical promotion, suggesting IGF-1's role in skin carcinogenesis.

In this study, researchers observed that intractable pruritus in anterior chest keloid lesions is linked to increased intraepidermal nerve fibre density and elevated expression of substance P, without differences in Langerhans cells across different keloid regions.

This study found that a transdermal delivery system using 3% azone and P407 gel may enhance the skin permeation of doxazosin and finasteride for treating benign prostatic hyperplasia.

This study found that treating human skin explants with TPA increased the number of certain melanocyte phenotypes in the interfollicular epidermis, suggesting that this ex vivo model can effectively replicate human skin's pharmacologic responses for studying potential treatments.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This research studied the effect of local testosterone propionate applications on rabbit epidermal mitotic activity but reports no new results.

This study demonstrated in rodent models that artificial dermal template treatment can induce full-thickness skin regrowth including skin epidermis and adnexa without the need for autologous skin grafts.

In this study, treating a rabbit with ear canker using ivermectin, pheniramine maleate, and a honey-turmeric mix resulted in substantial clinical improvement, including reduced itching and restored hair and skin quality.

This study found that transgenic mice with expression of HPV16 E6/E7 oncogenes showed improved ear tissue regeneration, including hair follicles and cartilage, without tumor formation.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This paper provides evidence supporting the formation of new hair follicles in adult humans, building on findings previously demonstrated in rabbits.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study reported that combining microdialysis and selective follicular closure with varnish significantly reduces caffeine penetration through hair follicles in an ex vivo porcine ear skin model.

This study found that a newly developed mouse ear punch model effectively demonstrated that radiation significantly delays wound healing and may be used to study combined radiation and wound injury mechanisms.

This study explores ear pinna development in mice and reports that elastic cartilage formation is disrupted in a short ear mutant, correlating with increased adult adipocytes and impaired chondrogenesis.

The document discusses various diseases of the outer ear, categorized by symptoms like redness, crusts, bumps, pus-filled lesions, lumps, ulcers, and hair loss.

Lichen planopilaris and frontal fibrosing alopecia are likely the same disease with different clinical appearances.

This study found that young C57BL/6 and BALB/c mice exhibit distinct regenerative patterns during ear wound healing, with greater wound closure but less regeneration in middle-aged C57BL/6 mice.
